The Infrastructure for Private Markets
Go from unstructured financial documents to structured, validated data in a single API call. Transform PDFs and excel sheets into constructed tables. Build the future of private capital. With Zero Errors.
from henon import Henon
client = Henon()
# Go from PDF to structured data in two lines
upload = client.upload(
file_path="quarterly_report.pdf"
)
result = client.extract.run(
input=upload,
schema_name="private_equity/quarterly_report/v1"
)
print(result.data["schedule_of_investments"])Why developers choose Henon
We're not a generic data extraction tool. We're the only API built from the ground up for private markets.
Domain-Specific Intelligence
Our models are pre-trained on millions of private markets documents. We know what a capital call, a K-1, and a covenant certificate are — so you don't have to teach us.
Zero-Error, Validated Data
Don't just parse documents — understand them. Our API performs financial validation and reconciliation out of the box, delivering data you can trust in production.
Developer-First Experience
World-class documentation, simple pricing, and powerful SDKs. We're obsessed with making the developer experience as frictionless as possible.
Built for financial use cases.
From fund administration to AI pipelines, the Ontology SDK powers the workflows that matter.
Automated Fund Admin
Ingest capital calls, distributions, and NAVs to automate your back-office. Go from PDF to structured data in seconds, not hours.

No need to define your own extraction templates. We've already built schemas for the documents that matter in private markets.
